8. Having defined the relevant market, it is to be determined whether OP 2 is dominant in the aforesaid relevant market or not. In this regard, it is observed that OP 2 had a market share of 90.92% in the production of VSF in the year 2014-15 in India and it has been consistently holding a market share of over 90% in the preceding four years. Further, it is observed that there are no other domestic manufacturers producing/ marketing VSF in the domestic market. Therefore, the domestic buyers are essentially dependent upon OP 2 for their requirements of VSF. Further, the Commission observes that as of 2014-15, OP 2 had a production capacity of 4,36,065 MT whereas the entire demand for VSF in India during the same period was 3,09,345 MT which is only 70.94% of the total production capacity of OP 2. It is observed that OP 2 has been maintaining over 30% to 31% of excess production capacity of VSF over and above the domestic demand thereby creating and sustaining effective barrier to entry in the manufacture and sale of VSF. Based on the above, the Commission is of the view that OP 2 is dominant in the aforesaid relevant market.
